Short answer

Internal Medicine (내과) is generally the first department to see for indigestion, as it covers a broad range of digestive complaints including bloating, nausea, and discomfort after eating. If symptoms persist or a more detailed evaluation is needed, you may be referred to a specialist within internal medicine, such as a gastroenterologist.

Which department

  1. 1Internal Medicine (내과)
    Internal Medicine is the standard first-stop department for digestive symptoms in Korea. Physicians here assess a wide range of conditions affecting the stomach, esophagus, and intestines, and can coordinate further evaluation if needed. — First / second line: In most cases, visiting a local clinic (의원) in Internal Medicine is the typical first step. If your symptoms are complex or have lasted a long time, the clinic doctor may issue a referral letter (진료의뢰서) to a larger hospital.
  2. 2Gastroenterology (소화기내과)
    Gastroenterology is a subspecialty of Internal Medicine focused specifically on disorders of the digestive tract. This department is particularly relevant when indigestion is accompanied by persistent or recurring symptoms that require specialized assessment. — First / second line: You would generally visit Gastroenterology at a hospital (병원 or 종합병원) level, often after being referred from a primary clinic. Some larger clinics may have a gastroenterology specialist on-site.
  3. 3Family Medicine (가정의학과)
    Family Medicine physicians provide comprehensive primary care and can evaluate indigestion in the context of your overall health, including lifestyle factors, stress, and other medications you may be taking. — First / second line: A Family Medicine clinic is a practical first option if you are unsure which department to visit, or if your indigestion may be related to general health or stress-related causes.
  4. 4Surgery — General Surgery (외과)
    General Surgery becomes relevant only when indigestion is accompanied by signs that may suggest a structural or surgical issue, such as a suspected obstruction or gallbladder problem. This is not typically the first department for routine indigestion. — First / second line: You would generally reach General Surgery through a referral rather than going directly, and only if an Internal Medicine evaluation suggests a condition that may require surgical assessment.

Go to the ER / call 119 if

If any of the following applies, do not choose a department — go to an emergency room or call 119 (Korea's emergency number).

  • Sudden, severe abdominal pain that does not ease — go to the emergency room or call 119 rather than choosing a department.
  • Vomiting blood or material that looks like coffee grounds — seek emergency care immediately.
  • Black, tarry, or bloody stools — do not wait for a scheduled appointment; go to the emergency room.
  • Difficulty swallowing accompanied by severe chest pain or a feeling that something is stuck — this warrants emergency evaluation.
  • Indigestion accompanied by sudden cold sweats, shortness of breath, or pain radiating to the left arm or jaw — these may indicate a cardiac emergency requiring 119.

Before your visit

  • Note when the indigestion started and whether it appeared gradually or suddenly, as this information helps the doctor assess your condition.
  • Keep track of what foods or situations seem to trigger or worsen your symptoms, including meal timing and portion size.
  • Write down any accompanying symptoms such as nausea, bloating, heartburn, belching, loss of appetite, or unintended weight loss.
  • Bring a list of all medications, supplements, and herbal remedies you are currently taking, including over-the-counter products, as some can affect digestion.
  • If you have had any prior stomach-related tests or procedures (such as endoscopy or imaging) in Korea or abroad, bring those results if available.
  • Be ready to describe your general stress levels and lifestyle habits, as these are commonly discussed during an Internal Medicine consultation for digestive complaints.

General principles

Indigestion — known medically as dyspepsia — is a broad term covering discomfort or a feeling of fullness in the upper abdomen, often after eating. In Korea's healthcare system, Internal Medicine (내과) is generally regarded as the appropriate first point of contact because this specialty is trained to evaluate both functional causes (where no structural problem is found) and organic causes (where an underlying condition exists).

The general flow of care for indigestion in Korea typically begins at a local clinic (의원), where a physician takes a history and may perform basic assessments. If initial management does not resolve the symptoms, or if certain findings suggest a need for further investigation, the patient may move up to a secondary hospital (병원/종합병원) directly without a referral, or proceed to a tertiary hospital (상급종합병원) with a referral letter — which is required at that level to maintain health insurance (건강보험) coverage.

In terms of diagnostic principles, a variety of tests may be considered by the attending physician depending on the nature and duration of symptoms — these can range from blood work to imaging to endoscopic procedures. The type and sequence of any investigation is determined by the clinician based on individual presentation, and no specific test should be assumed necessary without a consultation.

Because indigestion can sometimes reflect conditions in organs beyond the stomach — including the liver, gallbladder, or even the heart — the attending physician in Internal Medicine is generally well-positioned to determine whether your symptoms fall within their scope or require input from another specialty.

FAQ

Should I go to a local clinic (의원) or a hospital (병원) for indigestion?

In general, starting at a local clinic is the recommended approach for indigestion in Korea, as this aligns with the standard referral-based system and is typically more straightforward for initial evaluation. A clinic physician can assess whether a referral to a larger facility is appropriate based on your specific symptoms.

How is indigestion different from heartburn — do I see a different department?

Indigestion and heartburn can overlap but are not the same thing; heartburn typically refers to a burning sensation rising from the stomach toward the chest, while indigestion is a broader sense of discomfort or fullness. Both are generally assessed first by Internal Medicine (내과), and the physician will help clarify which condition is most relevant to your situation.

What kinds of tests are generally done for indigestion in Korea?

The types of tests considered for indigestion vary widely depending on a person's age, symptom duration, and accompanying signs — common general categories include blood tests, breath tests, imaging, and upper endoscopy. The attending physician determines which, if any, tests are appropriate during consultation, so no specific test should be anticipated without seeing a doctor first.

Is the approach different for children or elderly patients with indigestion?

For children, a pediatrics (소아청소년과) clinic is generally the more appropriate first contact, as pediatric physicians are trained to evaluate digestive symptoms in the context of child development. For elderly patients, Internal Medicine remains the standard first department, though the physician may take a broader view of contributing factors such as medications and overall health status — consulting a doctor in person is the best way to determine the right approach for age-specific concerns.
